Exploring the Chinook Culture Contact at Station Camp at the Mouth of the Columbia River

The Station Camp/McGowan site, at the mouth of the Columbia River, contains the remains of a contact-period Chinook Indian village characterized by abundant fur-trade era goods and well-preserved architectural features associated with at least three plank structures. The Chinookan fur-trade site (identified as the Middle Village by Chinook people) contains an abundance of wealth items and a dearth of productive tools and debris within traditional activity spaces. These data suggest the intensity and context of interaction between Native American groups at the coast and Euro- American traders

The Experimental Reduction of Rock in a Camas Oven: Towards an Understanding of the Behavioral Significance of Fire-cracked Rock

The selection and management of rock for roasting ovens, hearths, and sweat lodges were not trivial concerns for prehistoric households. The results of replicating a camas roasting oven are used to address the use-life and use-stages of fire-cracked rock. We concluded that the industry associated with the procurement and management of fire-cracked rock in the Pacific Northwest required significant quantities of labor and expertise to manage the raw materials and camas roasting byproducts. Recording the technological performance characteristics of fire-cracked rocks, including composition, size, and durability, is a necessary step to interpret and compare fire-cracked rock features at archaeological sites

The connective Morava K-theory of the second mod p Eilenberg-MacLane space

We develop tools for computing the connective n-th Morava K-theory of spaces. Starting with a Universal Coefficient Theorem that computes the cohomology version from the homology version, we show that every step in the process of computing one is mirrored in the other and that this can be used to make computations. As our example, we compute the connective n-th Morava K-theory of the second mod p Eilenberg-MacLane space.Comment: minor change of title and one sentence adde

The Wilson-Polchinski Renormalization Group Equation in the Planar Limit

We derive the Wilson-Polchinski RG equation in the planar limit. We explain that the equation necessarily involves also non-planar amplitudes with sphere topology, which represent multi-trace contributions to the effective action. The resulting RG equation turns out to be of the Hamilton-Jacobi type since loop effects manifest themselves through terms which are linear in first order derivatives of the effective action with respect to the sources. We briefly outline applications to renormalization of non-commutative field theories, matrix models with external sources and holography.Comment: 22 pages, Latex, 3 eps figure

Development of Lunar Highland REgolith Simulants, NU-LHT-1M,-2M

As part of a collaborative agreement between the U.S, Geological Survey (USGS) and NASA's Marshall Space Flight Center (MSFC) lunar highland simulants are being produced to support engineers and scientists in developing the technologies required to put a base on the moon by 2024. Two simulants have been produced to date: NU-LHT-1M and -2M (NASA/USGS-Lunar Highlands Type-l & 2 Medium-grained). Using starting material chiefly collected from the Stillwater Mine, Nye, MT, blending protocols were developed based on normative mineralogy calculated from average chemistry, for the Apollo 16 regolith. New technologies using a high temperature remotely coupled plasma melter were developed to generate both high quality and agglutinitic glasses that simulate the glassy components of the regolith. Detailed chemical, mineralogical and physical properties analysis of NU-LHT-1M indicate that it is overall a good surrogate for highlands lunar regolith (our new simulant LHT-2M has not be analyzed yet). The primary difference between 1M and 2M was the inclusion of trace mineralogy (phosphates and sulfide). Plans will also be presented on the future direction of the simulant project

Projected impacts of 21st century climate change on diapause in Calanus finmarchicus

Diapause plays a key role in the life cycle of high latitude zooplankton. During diapause animals avoid starving in winter by living in deep waters where metabolism is lower and met by lipid reserves. Global warming is therefore expected to shorten the maximum potential diapause duration by increasing metabolic rates and by reducing body size and lipid reserves. This will alter the phenology of zooplankton, impact higher trophic levels and disrupt biological carbon pumps. Here we project the impacts of climate change on the key North Atlantic copepod Calanus finmarchicus under IPCC RCP 8.5. Potential diapause duration is modelled in relation to body size and overwintering temperature. The projections show pronounced geographic variations. Potential diapause duration reduces by more than 30% in the Western Atlantic, whereas in the key overwintering centre of the Norwegian Sea it changes only marginally. Surface temperature rises, which reduce body size and lipid reserves, will have a similar impact to deep water changes on diapause in many regions. Because deep water warming lags that at the surface, animals in the Labrador Sea could offset warming impacts by diapausing in deeper waters. However, the ability to control diapause depth may be limited

Early Holocene Occupation at the West Lost River Site, Klamath County, Oregon

Excavations at the West Lost River Site (35KL972) provide new insights on early Holocene occupation of southwestern Oregon. The article focuses on the artifacts and specimens recovered from the site
